Specification of Letters Patent.

Patented Sept. 26, 1916.

Application filed March 13, 1916. Serial No. 83,901.

To a] Z whom it may concern:

Be it known that I, BERT L. DAvIs, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented a new and useful Massage-Machine, of which the following is a specification. 1

This invention relates to massage apparatus, one of its objects being to provide a simple structure which can be applied readily to a sewing machine so as to receive motion directly from the balance wheel of the sewing machine, the operation of the apparatus resulting in a rapid intermittent suction through a cup or the like which is designed to be drawn over the surface to be massaged.

A further object is to provide simple and efficient means for attaching the apparatus to a sewing machine.

lVith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings :Figure 1 is a side elevation of a portion of a sewing machine and showing the present apparatus combined therewith. Fig. 2 is an enlarged side elevation of the massage apparatus. Fig. 3 is a plan view thereof. Fig. 4 is an enlarged vertical transverse section through the massage apparatus.

Referring to the figures by characters of reference 1 designates a cylinder formed of the lower portion of a tube which is closed at its ends, as shown at 2 and 3, the intermediate portion of the tube being pressed inwardly as at 4 to form an overhang extending over the cylinder 1. Extending through the upper portion of the tube is a bearing sleeve 5 and journaled in this sleeve is a shaft 6 to which is connected a wheel 7 provided, preferably, with a tire 8 of soft rubber or like material.

A piston 9 is mounted for reciprocation within the cylinder 1 and has a rod 10 con necting it to a wrist pin 11 on the wheel 7, an intermediate portion of this rod being offset laterally as at 12.

Extending from the wall of the cylinder 1 near the lower end thereof is a nipple 13 to which is connected a flexible tube 14 the outer end of which is provided with a suitable massage implement such, for example, as a soft-rubber cup 15. Embracing opposed portions of the cylinder 1 are arcuate clamping members 16 the outer ends of which are adjustably connected by a bolt 17 so as to cause the members to bind tightly on the cylinder While the opposed ends of these clamping members are formed with extensions 18 riveted or otherwise connected as at 19 and spaced apart for the greater portion of their length to form a slot 20. Adjustably mounted in this slot is a bolt 21 having a finger 22 extending at right angles therefrom and under the extensions 18, the upper end of the bolt being engaged by a wing nut 23 designed to bear do-wnwardlvon the extensions.

Pivotally mounted on the bolt 17 is a leg 24 having a laterally extending foot 25 which can be provided with a covering of soft rubber or other suitable material. A similar leg 26 is pivotally mounted between the free ends of the extensions 18 and is also provided with a foot 27 having a soft covering of rubber or the like.

When it is desired to use the apparatus constituting thepresent invention, the finger 22 is inserted under the base plate A of a sewing machine head B so that the soft rim 8 on wheel 7 will fit tightly against the balance wheel 0. By tightening the bolt 21 by means of the wing nut 23 the parts will be held securely together and the feet 25 and 27 will be pressed firmly onto the top of the cabinet of the sewing machine. With the parts thus assembled the balance wheel can bedriven in the ordinary manner and will obviously cause the wheel to rotate at a high speed, this resulting in a rapid reciprocation of the piston 9 and, consequently, a rapid intermittent suction through the cup 15 and its connection 14. Thus by placing V the cup upon that portion of the body to be massaged, a rapid vibration due to suction and breakage of suction will be maintained equaled.

and all of the benefits derived from the use of expensive electrical appliances can be hat is cl med is 1. t Iassageapparatus for attachment to a sewing machindincluding a cylinder, an integral portion overhanging the cylinder, a wheel supported by. said overhanging portion and adapted for engagement with the balance wheel of a sewing machine to receive motion therefrom, a piston within the cylinder, a connection between the piston and sa1d wheel, a flexible tube 111 communication with the cylinder, a massage implement connected to the tube, and means connected to the cyllnder for engaging the base of the head of a sewing machine to hold the forming an overhang at one end of the tube, there being a cylinder at the other end of the tube, a flexible tube extending from the cylinder, a shaft mounted for rotation within one end portion of the tube, a wheel supported by the shaft and having a wrist pin,

a piston within the cylinder, a rod connecting said piston to the wrist pin, clamping members connected to the cylinder, feet attached thereto for engagement with a support, and means adjustably connected to the clamping member for engaging and pulling upwardly upon the base of a sewing machine head tobind the feet upon a support and hold the wheel incontact with the balance wheel of the sewing machine.

In testimony that I claim the foregoing as my own, I have hereto atiiXed my signature in the presence of two witnesses.
